Read a Call Number

Call numbers are the label on the spine or upper left corner of covers that organize materials according to their subject. When locating an item, you will need the call number and the location of the collection.


Our library uses Library of Congress (LC) for the majority of the collection and Dewey for the young adult and juvenile books.


The difference between the two systems is LC call numbers starts with letters while Dewey starts with numbers if non-fiction and with first letters of author's last name if fiction. The letters or numbers represent the subject category or author's last name.
